One of the oldest Florentine customs, well-known during the Renaissance, was the annual Calendimaggio Festival. On this day, young men got up early and decorated their sweethearts’ doors with branches of flowering shrubs, decorated with ribbons and sugared nuts. The girls, wearing pretty frocks and carrying flowers and leaves, danced to the music of lutes in the very elegant Piazza Santa Trinita.
According to Wikipedia:
“In Italy it is called Calendimaggio or cantar maggio a seasonal feast held to celebrate the arrival of spring. The event takes its name from the period in which it takes place, that is, the beginning of May, from the Latin calenda maia. The Calendimaggio is a tradition still alive today in many regions of Italy as an allegory of the return to life and rebirth: among these Piedmont, Liguria, Lombardy, Emilia-Romagna (for example, is celebrated in the area of the Quattro Province or Piacenza, Pavia, Alessandria and Genoa), Tuscany and Umbria.
This magical-propitiatory ritual is often performed during an almsgiving in which, in exchange for gifts (traditionally eggs, wine, food or sweets), the Maggi (or maggerini) sing auspicious verses to the inhabitants of the houses they visit. Throughout the Italian peninsula these Il Maggio couplets are very diverse—most are love songs with a strong romantic theme, that young people sang to celebrate the arrival of spring.
Symbols of spring revival are the trees (alder, golden rain) and flowers (violets, roses), mentioned in the verses of the songs, and with which the maggerini adorn themselves. In particular the plant alder, which grows along the rivers, is considered the symbol of life and that’s why it is often present in the ritual.
Calendimaggio can be historically noted in Tuscany as a mythical character who had a predominant role and met many of the attributes of the god Belenus. In Lucania, the Maggi have a clear auspicious character of pagan origin. In Syracuse, Sicily, the Albero della Cuccagna (cf. “Greasy pole“) is held during the month of May, a feast celebrated to commemorate the victory over the Athenians led by Nicias. However, Angelo de Gubernatis, in his work Mythology of Plants, believes that without doubt the festival was previous to that of said victory.”
